In general I think that is true. But in this particular case, that experiment is just there to work around unfortunate decisions made in the past. I can understand that it is now a lot of work to re-work the German HAMNET to make it compatible with a plain routed address space, but I do not see it as my responsibility to jump through hoops instead.
Here, we are starting from a blank page. And we are an island. Usually, it's not an advantage, but here, it is :-) We can build our network as an internal, closed network. And we can manage the routing issues with the rest of the world at our gateway level. I think we should be able to implement routing with everything (including IP-IP mesh tunnels).
We use OpenVPN only for end-users that connect to our gateway and get 44Net space but only over the tunnels. However, that is the "novice class" of AMPRnet, we really do not want users to connect that way forever. They should use radio links, and when no access point is available they should get together and establish one. And that is developing rapidly.
+1. But it may be easier to do in flat areas with many hams :-) For now, even our main high points are not in line-of sight :-( We are using tiny VPN boxes behind Internet accesses at low points to feed 5 GHz antennas to the high points... But of course, our goal is not to build VPN networks, HI :-) Radio links must (and will) be used whenever possible. We are still in experimental process (migrating from private addressing to future AMPR adressing). That's why we focus on the network infrastructure and design for now. Once our design is stable, we'll deploy more sites and users, with low cost 5 GHz dishs.
Of course if you want to setup many gateways like that across a larger country, the practical difficulty is that you need to negotiate BGP routing in many places. It is so much easier to just give in on that and go out via NAT over some local amateur's internet connection.
As said before, we are a tiny island of 320 000 people, which makes the problem a lot simpler. Our network will have an "internal" routing (we may keep our existing OSPF), and an "external" routing, with exchanges between the two at the gateway level. As we have two network teams, and two data centers, in the main cities of the island (Ajaccio and Bastia), we can afford two gateways, and a fully redundant design, HI :-)
